Display device and array substrate

A display device comprising:

• a substrate;
• a plurality of pixels provided to the substrate;
• a light emitting element and a plurality of transistors provided to each of the pixels;
• signal lines configured to supply a signal to the pixels;
• a first semiconductor layer and a second semiconductor layer provided in different layers in a direction perpendicular to the substrate and overlapping at least partially in planar view;
• first gate electrodes each of which is provided in a region overlapping a part of the first semiconductor layer;
• a first insulating film provided between the first gate electrodes and the first semiconductor layer;
• and
• a second insulating film provided between the first semiconductor layer and the second semiconductor layer, wherein
• the transistors each include a first transistor and a second transistor,
• the first transistor comprises the first semiconductor layer and supplies an electric current to the light emitting element,
• the second transistor comprises the second semiconductor layer and is coupled to the first transistor,
• the first transistors each comprise one of the first gate electrodes overlapping the first semiconductor layer, and
• the second transistors each comprise two second gate electrodes overlapping the second semiconductor layer.
